Journey of Success: EMWorks Inc. & Team Zeus





If you go to the University of Calgary you don’t suffer from a lack of choice when it comes to Students Union clubs. There are options for everything from swing dancing to politics to Bronies. But the most interesting club in our view is one called Team Zeus. It’s only three years old but these undergrads are building an electric racing motorcycle.

“For me I’ve always been really fascinated with electric vehicles. I like the idea of being involved with a new up and coming industry… There are still huge advancements being made every year,” says Siegfried Baumann, the past president of the group.

“I feel like if I worked with regular gasoline motorcycles I could work my entire life as engineer to increase the efficiency by one percent. Whereas with electric vehicles it’s doubling every year, it’s a very exciting time.”

Baumann is a third year mechanical engineering student who just scored a yearlong internship with BMW’s electric vehicle division based mostly on his work with Team Zeus.

The group’s goal is to get their electric bike, called the Zephyr, on a racetrack this summer. It’s being built on a Suzuki GSXR 600 racing bike frame that’s been stripped down and rebuilt as an electric motorbike.

And the race they will be participating in isn’t some endurance race where we see who developed the best batteries. Like MotoGP and Formula One this is all about sexy machines going as fast as they possibly can. Team Zeus is aiming for a top speed of 160 km/h and a range of 20-30 kilometers.

The biggest difference between electric motorbikes and their gas-powered brethren is the transmission, or lack thereof.

“Most electric bikes don’t have a transmission at all they just directly connect the motor to chain so essentially so there’s no gear shifting. The torque is quite noticeable. Once you twist the throttle you go basically. It catches a lot of people by surprise the first time they ride it,” says Baumann.

The result is exhilarating: no gearshift, no pushing in the clutch and just instant power from the moment you twist the throttle.

The group got its start from watching the movie Charge. The documentary follows several teams on their way to the world’s first electric motorbike grand prix on the Isle of Man in 2009.

“We were all really inspired by this and we decided hey why we don’t do that. Our first prototype was done on a budget of a thousand dollars,” says president Christine Hughes.

“We had an old bike that didn’t work, we took out all the mechanical parts, and we had some batteries donated to us by the solar car team here. We used a motor from a washing machine essentially and put it all together and it ran that was really exciting for us.”

That old ‘82 Honda was dubbed the Mule. While it won’t win any races with a top speed of 20 km/h, the group proved it could build a working electric motorbike. If the Mule is the golf cart of electric bikes then the Zephyr is their Tesla.

The cost of the bike and getting to the race will be around $25,000 and they recently held a successful Kickstarter campaign that raised more than $4000 with the Schulich School of Engineering will partially match the funds. They’re.

They’ll be competing against groups that will spend hundreds of thousands of dollars on their bikes. But it’s not about the money or even the credits.

“It’s all extra-curricular but I think I’ve learned more from Team Zeus than from a lot of my courses,” says Hughes. “This is cutting edge, brand new technology. We’re actually getting in here with professionals who are doing the same thing and making the same mistakes we are.”

Hughes is a fourth year mechanical engineering student and she’s looking to take her Team Zeus experience and apply it to the next big up and coming industry, clean energy.

“A lot of the skills I’m learning are so transferable – How to manage your project, how to actually design something that will work. That’s been huge. And also learning on the electrical side of things I’m really interested in sustainable energy and the motors that we’re building have lots of applications. Wind turbines use the same kind of technology to generate power and I would love to get involved with wind energy or something similar,” says Hughes.

Electric motorcycles are already on the market and much like electric cars they’re marketed as sleek, sexy, environmentally friendly city runners. And advancements made on the track shouldn’t be discounted either. It’s because of F-1 racing that we have things like disc brakes and traction control. The advances made by the teams participating in these electric motorbike races in miniaturization, propulsion and battery technology could have massive knock-on effects in electric vehicles.

How EMS helped them build their electric motor:

The Zephyr will be our first official racing bike that will aim to compete in the TTXGP this August, 2014, at a race in Salt Lake City. This will be a fully race-worthy bike brimming with horsepower, torque and overall badassery.  As part of our overall mission statement, we don’t just want to put to together a few off-the-shelf components, but strive to learn and innovate, so we have taken it upon ourselves to design an in in-wheel electric motor from scratch.  As far as we know, only one other race team has taken the in-wheel-motor approach, and we feel it is a very open ended and exciting area to explore.  Using the skills we learned from building the Axel Borg Motor, we are well aware of the challenges ahead but are determined to see it through.  This will be mounted on converted gasoline bike frame.

After a lot of research and searching we finally settled on a 2004 Suzuki GSX 600.  This bike came straight from the factory as a full fledged race bike and was never intended to be street legal.  The former owner used to be a racer as well, so this bike already has a fast and furious past.  The open frame design gives a lot of flexibility with mounting our components and the lightweight aluminum construction is perfect for our needs.  We have already stripped it down and plan on selling the gasoline engine and all its components.

For our first iteration, we will be using two Agni 95-R motors coupled together, with direct chain drive.  We will be using a Kelly controller and Lithium Ion cells carrying approximately 7.5 kW hours.  Our main objective here is to make a working bike and racing, for the experience, so we can go on to our much more ambitious second generation.

The second generation will focus mostly on the development of our own in-wheel motor and a complete retooling of the batteries and controller to take advantage of this new layout.

Motor :Our aim is to build an axial flux, brushless DC, 3-phase motor.   We are exploring a lot of different avenues in terms of magnet array geometry, coil arrangement and geometry, cored vs. uncored coils and single vs. double stator designs.  Due to the nature of electric motor design, it is difficult to update with small steps, as everything is so intertwined that changing one thing changes everything else.  We basically need to research our way into a magical combination of two or three viable arrangements and then do simulations to refine from there.  Here are some concept sketches and models that have come out of our research thus far:

Some of the initial concept sketches during brainstorming of the mechanical portions of the motor.

Our first CAD model to get an idea of the rough dimensions and fits of the motor.  This design is likely, but may still change if our optimization studies find that a double stator design or cored stator design might turn to be markedly better.


One of our many magnetic flux density studies performed potential permanent magnet arrays.  We are considering both standard arrays and Halbach arrays, which offer more challenges but some very exciting new ground in motor design.

03/13/2013:  “The software has been very helpful so far, getting an idea of the linear magnetic flux density of various magnet configurations.  It is far superior in user friendliness than Ansys was.  Sadly our old club computer is rather slow at running calculations, so we are trying to do more hand calculations to narrow down our options that we need to simulate.  Overall, I’d say we’re all very happy with the software“…

04/10/2013:   “I just tried out EMWorks the other day and its seemed to work fine without asking for a new access code or anything, so everything seems to be OK“…

05/13/2014:    “Would still be delighted to co-author a White Paper………but obviously we will be putting our main focus on assembling our current off-the-shelf motorized bike for the next four months, before we resume the motor design.

08/27/2013:   “We hope we can collaborate more in the future though. Thank you for your continuous support!”

They are talking about us!

…A Lorentz force linear motion actuator was built to deliberately exhibit a highly nonlinear current for force relation even when the coil was completely immersed in the magnetic field. Magnets were arranged radically around the coil but only half the permissible number were included in order to generate a more complex actuator configuration to test the ability of the

EMS electromagnetic finite element analysis software to handle more challenging magnetic path geometries. A detailed set of experiments were carried out on the actual actuator and a similar set of analyses were undertaken using the EMS magnetostatic electromagnetic finite element analysis software. EMS correctly accounted for the gross nonlinearities in the current to force measurements…

Ian Hunter: MIT

We have heard about the EMWorks software as a result of searching for Finite Element Modeling (FEM) software which would be adequate for our purposes. After the review of various offers we stated that EMS has all features we need. The great advantage of this package is that it is based on SolidWorks. Thanks to this design of even very complex models becomes child’s play. My first magnetostatic model in EMS was created in just a few minutes! I highly recommend EMWorks software for all those who need friendly interface as well as professional FEM software…”

“Currently we are optimizing Pipeline Inspection Gauge (PIG) with Magnetic Flux Leakage (MFL) system to evaluate technical condition of pipelines. Such system consists of magnetizing yoke and magnetic field sensors. Working PIG can reach velocity of even 10 m/s due to liquid media pressure. Our job is to model effect of velocity on eddy currents generation and hence distortion of MFL signal.

 “We’d just like to thank EMWorks for generously donating their electromagnetic simulation software to us. Now we can actually refine the finer points of our motor!” 

“I used the AC Magnetics module within the EMS software to model electromagnetic coupling to a lab-scale molten metal charge.  This modeling was meant to investigate the efficiency and efficacy of inductive coupling as a means to heat and stir a metal solvent for a high temperature crystal growth process.  I found the software to be well integrated with SolidWorks, with intuitive menus and feature commands.  The array of parameters available for adjustment was quite broad; I was able to easily set up a good proxy for my actual experimental setup.  The ability to copy/paste an entire study in one step made it especially quick to vary parameters and compare results.EMS software represents a powerful and robust tool for anyone conducts research, design or development of systems involving electromagnetic.”

”The installation of EMS for Inventor is very easy; it also has a lot of analysis options. The interface is intuitive and clear. EMS for Inventor allows for fast and accurate linkage analysis in the field of electro-thermal and magnetic as for the design of highly complex projects is very useful. EMS saves time and avoids the problems associated with the transformation of files between different programs – in this way we gain time, which in the case of very complex analysis is priceless. The Support Team of EMWorks is very professional and very helpful – if an error is detected; the reaction and giving solution is very fast…”
